Most likely you'll have the same experience with/without encryption. Look
for a hardware problem.
If you don't find a hardware problem, look deeper. For example, maybe
there's only a few bad sectors on disk, and you happened to hit them when
you ran encryption. So if you don't find the problem repeating the same
test without encryption ... Use a larger data set, up to the size of the
entire pool.
Probably the fastest and easiest... Run something like memetest86 to test
all your RAM. Are you using ECC ram? You could probably skip the memtest
safely if you have ECC.
If that still doesn't yield any results, try stressing & overheating the
CPU doing unrelated work at the same time while you're repeating your disk
test unencrypted. 16-threaded infinite random number generator dumping to
the null bucket, while you're running your disk test without encryption.
That should be a pretty exhaustive process to check your CPU, memory,
motherboard & buses, disk controllers, and disks. I bet you'll find some
hardware issue.
